REMOVABLE-SIDED INGOT-MOLD.

Specification of Letters Patent.

Application filed October 21. 1913. Serial No. 259.082.

To all whom it may concern:

Be it known that I, RAY G. (learns, a citizen of the United States, and a resident of the city of Pasadena, in the county of Los Angeles, State of California, have invented new and useful Improvements in Removable-Sided Ingot-Molds, of which the following is a specification.

This invention relates broadly to metallurgy and more particularly to an ingot mold.

The principal object of the present in vention is an ingot mold provided with removable portions and so constructed that the parts may be standardized in such. manner that corresponding; parts of diil'erent molds are interchangeable, whereby economy in manufacture and labor is facilitated.

A further and equally important object of the present invention is an ingot mold of the character specified, wherein the sides of the ingot preferably are Without draft whereby the ingot may be more readily treated by rolling or forging than if the sides were tapered or inclined, and wherein one end of the ingot is adapted to he at substantially right angles to the axis of the ingot so that the said ingot may be set in an upright position in a soaking pit.

A still further object of the present invention is an ingot mold of the character specified wherein the mold is constructed in such manner as to facilitate the casting of ingots several sizes smaller than the maximum size for which the mold is designed and also wherein the top of the mold is without obstructions so that no part of the mold will interfere 'With any desired apparatus for keeping the top of the ingot fluid While other portions are crystallizing. V

A still further object of the present invention is an ingot mold of the character specified and being provided with hinged at substantially right angles to the axis of I the ingot.

The present invention possesses many other and advantageous features some of which together with the foregoing will he set out more at length in the following description wherein will be outlined in full that form of the invention which I have selected for illustration inthe drawings accompanyingand forming a part of themesent specification.

In the drawings and specification I have disclosed only the preferred form of my generic invention, but it is'to be understood that I do not limit myself to such form because my invention may be embodied in a multiplicity of forms each being a species of my invention, it being understood that by the claims succeeding the description of my invention I desire to cover-the invention in whatsoever form it may he emhodie and practised.

In the drawings like characters are used to represent like parts throughout the several figures thereof.

Heretofore in the steel art it has been customary to form steel ingots from which rolled or forged steel articles are manufactured, and it has been the practice to cast these steel ingots in tapered vertical molds. These molds haye been made of iron alloys and constructed of such thickness as to chill the ingot and since the chilling progresses from the walls of the mold inward, the ingot often has defects in the center thereof which are known in the art as pipes. in order tov facilitate the removal of the ingot "from the mold the sides of the mold are tapered and the resultant ingot necessarily is tapered. The taperingof the ingot interferes to a certain extent with the rolling operation, in that the rolls must he first set Patented Aug. 19, 191%.

the holes 9 to accommodate the larger portion of the ingot and then gradually closed to roll the smaller portion of the ingot. By this operation it is obvious the larger portion of the ingot undergoes more rolling than does the smaller portion, consequently the texture of the resultant product is not entirely uniform. Because of roughness on the interior of the mold and for other reasons it is not uncommon for the ingot to stick in the mold, and the molds are usually subjected to severe treatment in order to loosen the ingot. Because of this rough treatment the life of ingot molds is relatively short and the problem of furnishing adequate ingot molds becomes an item of considerable expense in the steel industry. a

The present invention overcomes the amculties of the known art by providing an ingot mold which produces a straight sided ingot of substantially rectangular crosssection and wherein: the ingot is released from the mold by loosening or removing the sides of the mold. This action obviates sticking of the ingots in the mold and obviates the necessary rough treatment. for removing the ingot. Furthermore, because of the fact that the mold comprising the present invention is made. up of interchangeable parts, it any portion of the mold is injured it is not necessary to destroy the entire mold since the injured part may be removed. Also since the ingot is cast on one side instead of one end the formation of pipes and defects is eliminated.

The preferred form of the mold consists of a body 1 having integral ends but open at the sides, which latter are adapted to be closed by side members Q'hinged to the body member. The body carries lugs 4- at one end and the side members are provided with coacting lugs 5. Holes 6 are cast in these lugs and rods 7, acting as pintles, are inserted in the holes. The combination forms a hinge for each side and allows the side members to be swung laterally so as to free the ingot and allow the ingot tongs to take hold of the ingot. The body is provided with cast in staples 8 and the side members are cast with holes 9 so that when the side memhers are swung against the seats on the body will pass over the staples 8. Wedges 11. can then be driven under the staples so as to wedge the side members to the body. in order that the side members may come to a free contact with the body the holes 6 through which the pintles 7 pass, in the lugs on the side members, are cast oval in horizontal section and with their long diameter normal to the plane of the side member. This allows lost motion to the hinge in a direction normal to the plane of the side member, and also permits the side member to fit snugly against the body without any strain on thehinge. The oval shape ,see

to the holes 6 allows no lost motion in the direction of the plane of the side members, consequently the pintles sustain and guide the side members so that they readily pass over the staples and do not strike on them. When both side members are closed and the wedges 11 are driven under the staples the wedge 12 may be inserted and driven between the locking arms 14 and 15 at the right end of the mold, thereby tightening the ends of the side members in one operation. The above mentioned lost motion in the hinge allows this action. Wedge 12 should not be tightened until the staple wedges 11 are driven up in order that the joint at the bottom may be tight and secure. The joint between the sides and the body when desired or necessary may be made tight by a clay, or other, luting.

In opening the mold the staple wedges 11 are driven out and the sides swung open and the wedge 12 is loosened when the sides swing out angularly. From this it will be clear that the action of the wedge 12 is to swing the side members on the pintles; therefore it should not be driven up until after all of the staple wedges 11 are driven in. It will be noticed that all of the side wedges are arranged to be driven horizontally. The reason for this is that when the parts are hot it is not desirable to handle them. In the arrangement shown these wedges may be knocked out by a blow of a sledge and yet at the same time there is no tendency of these wedges to fall out. From-the preceding it will be observed that by knocking out a few wedges and swinging the side members a foot or so the ingot tongs may readily grip the sides of the ingot and hit it from the mold.

In the vertical molds a small variation in the depth of the metal poured into the mold does not make much diderence inthe weight of the ingot, but in a horizontal mold the horizontal section of the metal is so much larger that a small variation makes quite a large difierence in the weight of the ingot. The notch 16 at the left of the body is an overfiow warning. It is made deep enough to overflow for the minimum size of ingot de sired from the particular size of the mold. The notch 16 may be dammed as desired,

with loam or clay so as to overflow any desired intermediate size of ingot between the minimum and maximum sizes. It is somewhat diilioult to judge the depth of hot metal in a mold. In using my mold, the metal can be rapidly and safely poured into the mold and promptly shut ofi when the first signs of an overflow appear at the notch, and an ingot of predetermined weight is thus obtained. The very small tail of metal that cools in the notch and is attached to the ingot does not interfere with the rolling since it is at the extreme end of the ingot.

From Fig. 1 it will be noted that the right interior end 17 of the mold is square with the inner bottom surface while the left end 18 has considerable draft. If the left end of the ingot is raised by the ingot tongs gripping the ingot on its sides the draft shown on the left will allow the ingot to up end freely, and it will stand upright on its square right hand end when placed in the soaking pit. The side may or may not be given draft for when the sides are open all side contact with the ingot is removed, but as stated the sides preferably are straight to provide an ingot of recta gular cross section.

Since the sides and the body are made to a, standard the breaking or damage of a part of the whole mold will require the replacement of only that part, A. new side or sides; a new body member on old sides; or the assembly of two old but good sides with an old but good body, are all practicable procedures. This feature will allow a long life to the mold. Furthermore since the strains of stripping are removed by not moving the ingot parallel to any draft surface there is little damage to the parts in the stripping operation. This fact coupled with that of the renewal of the parts will give a very greatly increased life to a given amount of metal cast into these molds over the same amount cast into molds of the vertical pattern.

The gravity Contact area between the ingot and the mold is one long side instead of merely an end, as in the vertical mold, and therefore is much greater than where the only gravity contact is one end of the ingot as where the ingot is cast in a vertical mold as is common in the art.

In Fig. 5 is shown an ingot in accordance with my invention wherein the sides 19 and 20 are substantially parallel, with the end 21 inclined and the end 22 at right angles to the axis of the ingot. The top side 23 of the ingot has been'out of contact with the chill mold and therefore is the only rough side of the ingot. This side is very easily treated or removed in the final treatment of the ingot. in view of the relatively large horizontal area ofthe ingotas compared to the vertical dimension there is more and better opportunity of the gases, freed during cooling of the metal, to escape. As pointed out the inclined end 21 on the ingot facilitates removal from the mold and the squared end 22enables the operator to stand the ingot upright in a soaking pit.
